This is the sort of thing I've wanted to write for a long time. Yes it looks like this is vibe coded but I'm glad this was made because it's cool to see what can be done, and it's interesting seeing how AI can be used as a compiler essentially given the output is assembly.
I'd be interested if the author would tell us more about what they did here and what went into the design and evolution, rather than the AI README.

I had fun playing around in Claude getting it to write 6502 assembler for the BBC Micro. It is fun to imagine what we could have built on those old machines with these new coding agents! But it is kind of hollow isn't it.

I think it's an issue for hobby projects. The other day I had a neat idea, looked into it and realized I would not have time to do it but still wanted to use it so I vibe coded it over an evening and there it was. But the code is not mine, I feel bad about it, it's completely hollow, I wish I had the time to do it properly. I'm glad I'm still hand coding my main hobby projects to avoid that.

Not for me. I do like having an agent at my disposition that accelerates the way into making those little experiments a reality. A sloppy reality? Maybe. But It's just tinkering, there's no other use case for this outside of saying "So this can be done, huh? Okay time to go to for a walk".
While it's totally respectable to treat your code as your personal zen garden, I like the idea of having a highway where I can make reality anything that comes from my imagination, and also having time for family, friends, work and exercising out of sedentarism.

It's the difference between building a table yourself and telling someone else to build a table for you.
If you've never done anything for yourself, usually with your own hands, you don't understand the pleasure and satisfaction that comes from doing it.
And since "AI" isn't human, it can't know that feeling, either.

Designing a table and letting somebody else build it can be enjoyable, too.
There are plenty of people enjoying designing, for example people who 3D print objects they design, or people designing PCBs or even entire gadgets but outsourcing production.
With LLMs, I guess a factor is how much direction you give the machine. “Build me a graphical desktop” likely isn’t very enjoyable, but I can see co-working with a LLM being enjoyable. Examples
- think of some novel UI interaction, and let the LLM code it
- spending hours to speed up the GUI or to make it use less memory

This.
Knowing your limitations of building, but being good at designing and watching somebody/something else realise your vision is incredibly satisfying.
I see it like 3D printing. Nobody can extrude molten plastic out of their bodies to make things, but the skill of designing the construction well and then watch the machine execute it is certainly a good feeling. I dont really see how this is different to designing some software verbally and prompting an ai to build it for you.

You can say the same for building computers. You didn't actually "built" a computer from the ground up. You just bought the pre-made hardware and plugged it in the places that are made to be easily pluggable.

That’s an absurd thing to say.
Doesn’t matter what “AI” feels or doesn’t feel. AI is a tool. You can derive as much pleasure from having an ideia, planning it, working on it from a higher level, and seeing it come to life as you do when you get down and dirty with it and do it from the low level up.

You are arguing against a very well known phenomenon. Technical people often avoid getting promoted to management precisely because they love doing the thing themselves. Despite the higher potential for impact in a management position, losing the detailed view of a practitioner is a real loss. This phenomenon is less obvious in big tech because there are so many people who really wanted to be managers the whole time, but had to be engineers first or never really cared about the work, but want a promotion for the better pay.

You either replied to the wrong comment or didn’t and proved my point exactly: some people like the technical low level approach, others prefer the higher level architectural work.

Wow I did so many of those when i was 12 or around that age. Mostly I tried copying the Amiga Workbench on my +2A (the gray one).
Obviously at that age my knowledge of coding and window managers wasn't exactly deep and i mostly only had seen other OS from magazines. I don't think I even knew what 'drag-n-drop' was and was a bit confused at what the Trash bin should do (i loaded code from tapes).

Long-form comments in the code are AI-written too, so I assume the whole thing is vibecoded. I guess my question is why. This is obviously not a piece of software anyone will ever use. If the author didn't do this for themselves - to learn, to show off their skills - then why bring it to life?
In business, there's this saying that "when a metric becomes a target, it ceases to be a good metric". I guess LLMs also make that true for hobby projects that used to make up a good portion of HN. We'd celebrate a project like that not because it's useful, but because it's a triumph of human ingenuity and a celebration of a personal achievement for the author. But now, it isn't, so is it still something we ought to celebrate?

Like many things in life, the answer is just "because I want to" and "because I can". Not everything has to be a linear progression or a level-up mechanic like a mmorpg.
Sometimes you want to create something out of creativity and you like seeing it done. The same way a painter wants to create something, not to show off skills, not to linearly progress onto something, but because they like making something out of nothing.

Well it’s more like commissioning art than making art yourself right? You want a painting of some specific thing to exist, so you find an artist you like and pay them to make it.
It’s not art, but I recently commissioned a translation of a manga that I wanted to read in English. The process was very similar to working with an LLM, just more expensive and the turn length was longer (and of course the output quality is much higher than an LLM generated scanlation would be at this point in time). I would pay for a chapter, he would send me a draft, we would go back and forth iterating on romanization and fixing typos until I was happy, then we’d move onto the next chapter. I achieved my goal of having the manga readable in English when it wasn’t before, but I wouldn’t call it my project.

I don't buy into the AGI commercial hype, and I treat LLMs as nothing more than pseudo-random text generators.
It just happens that at certain size the flow of words look a lot like "reasoning" because of the emergence phenomena (https://en.wikipedia.org/wiki/Emergence). But they do not have a theory of mind, they can't visualize and they do not have a sense of purpose.
Agents are not people.
42 minutes ago
A very significant difference is that AIs are programs, not people.
Perhaps it might be because i don't use any cloud LLMs, but the LLMs i use are all just data for a program running on my computer just like any other program and i don't really see them as any different than running -say- Bison to write a lexer or whatever (sure, Bison gives you the same output for the same input, but that is because LLM inference engines just add some randomness in the mix as that works better for the overall output - again, not any different than, say, rendering a 3D scene with a pathtracer that takes random samples: same input, different output -- or really any other thing that involves randomness).
That the combo of an LLM inference engine and weights kinda writes like a human and works with text in natural languages doesn't mean it is any different than any other piece of software.
I mean, i don't know about you but personally i'm not a fan of the idea of commissioning GCC to compile my code or Awk to process my text - even if i suspect there are business people out there who would love it :-P

Why not? The author wanted it, and had wanted it for about four decades since trying and failing as a child due to the difficulty of the task. If you’re in a certain frame of mind, then “why bring it to life?” can be directed at any kind of cultural work to negate it out of existence.

You're only addressing one half of my argument. The answer to this is obvious: the default state is that things don't get done unless we have a reason. So there is a motivation at play and it's perfectly OK to inquire about it, especially if the author appears to be cagey about how the project came to be. If your answer is "it was the author's childhood dream", fair.
But that brings me to the second half of the argument: I think we upvote this article in large part because of the historical association of a "crazy 8-bit software project" with "something that took perseverance and skill and our community should reward it". That link is severed now.

What about art? People make art and inventions just for the hell of it and to satisfy come itch. Whether or not other people then like it or find it useful is subjective and up to the individual. IMO taking away peoples right to make stuff for no reason and enjoy doing it is to take away our humanity.
I upvoted the article because it brought me some nostalgia and entertained me for a bit while I played with it and knowing how to code a spectrum myself, marvelled at the complexity of the code and the project itself. Maybe people have more reasons to enjoy things than your narrow viewpoint allows for?

There’s the problem: you are assuming everyone else thinks in elitist terms like you. It still is a crazy 8-bit software project. It still rather impressive and fun to see.
Your “historical reason” reads a lot more like whining than anything else and it does come across as a display of insecurity.
AI is just a freaking tool. The dev used to tool to bring his vision to life. That’s the extent of it. Stop making such a fuss over something that quite literally was just made for fun.

My best theory would be it's something that was built as like a novelty/proof of concept, that a current state of the art LLM can do tedious tasks like assembly on a ridiculously old/low resource platform and turn out something that actually looks coherent. I don't personally know a lot of people who enjoy building large things in assembly but LLMs aren't bothered by doing tedious tasks. Due to the tiny size of the thing it can probably very rapidly iterate on "this doesn't work, change a thing, run it again" thousands of times.

If you’re familiar with the way in which documentation artifacts like this fall out of a Claude project, you will recognize that every place where Claude says ‘this changes everything’ or ‘this is the load bearing insight’ most likely resulted from a human looking at what Claude had done, and redirecting it towards a more fruitful line of inquiry. When Claude gets ‘excited’ about a thing like ‘we figured out which clock measurement approach helps us actually optimize performance’ - excited enough to explain it in this level of detail - it usually results from the user pulling Claude out of a rabbit hole where it was going about things the wrong way.

I think all AI projects should die, but if your question is aimed as to "why to publish it on github", then why not? Others could look at the code and learn from it (perhaps); and it is easier to distribute it that way too, in many cases. So I don't fully agree with the assumption that it would be automatically useless. Personally I won't use AI slop projects. It already annoys me to no ends that AI skynet successfully took over ruby development. I don't feel like even giving any feedback, as a few ruby devs such as Hiroshi Shibata, only interact with other beings via AI slop spam via claude; suddenly newly gained "perfect english language skills". It is all so fake now when AI infiltrates projects.

So coding is only valid when it “enriches the coders skills and experience”? How do you define those? Better yet, WHO is defining those? Are you so narrow minded and decidedly contrarian that you simply refuse to think of any other reason the dev might’ve done this for? I don’t wanna tell you you need to touch grass but goodness me you really ought to consider opening your mind to the fact that you are not the centre of the universe.

I wonder: was there a time when using a compiler was considered cheating? "Real men" code everything in ASM!
I do recall a whole era when using a GUI was considered cheating and denigrated as a "point and drool" interface (a play on "point and click").
Is using a combine cheating in farming? Is a nail gun or using prefab wall sections cheating in home construction? Is a 3D printer cheating in fabrication? If someone prints something with a 3D printer, do we say "you didn't make that, the printer did!"
I find it weird for people who like technology to be so averse to tools that automate labor since that is literally what all technology is, and a tool to automate intellectual labor is literally what a computer is. A machine is a thing whose purpose is to provide leverage to amplify human effort and more rapidly realize human intent in some domain.
Maybe it comes from a category error. AI is kind of a hand-wavey term, since most people think it means the thing is sentient. It's not. It has zero intent, zero motivation, zero ability to choose anything not already in its training data, and it will go precisely where its context window (and training data) guide it. It's a tool, a machine, and like any other machine it is set in motion by the user and guided by the user. The "choices" it makes are latent in its data or structure, or implied by its prompt. (Yes sometimes they can be surprising, but that's true of all complex machines.)
Actual sentient AI does not exist. It might someday but it does not today. I suspect it requires a very different kind of system with continuous learning, dynamical state, and feedback, and a goal function tied somehow to thermodynamics in the real physical world the way ours is, but that's pure hypothesis on my part. We don't even have rigorous definitions for such things.

It’s Claude’s earnestness that’s so disingenuous in this kind of write up. This voice Claude has where it believes the work is important and deserves to be taken seriously, and where it takes ever part of the process where it has to adjust its approach because of a thing it figured out as a great insight which is incredibly valuable and that people should be made aware of…
I feel like vibecoded projects need Claude to pick up on a sense of ‘this is just me messing around’, and a project like this where there does appear to be genuine digging into the art of performance tuning Z80 assembly needs Claude to understand ‘this is impractical hacking for hacking’s sake not groundbreaking research’
I don’t have a problem with projects which are, essentially ‘Claude and I burned a lot of tokens for giggles to see just how far you can push something’. But the write up needs to reflect that spirit.

Assembly seems overkill though.

There is practically no other choice on a Z80. C compilers really don't like the Z80 ISA and create both slow and bloated output, at least compared to manually written asm. And on top, you can do many optimization tricks in assembly that simply are not possible in a high level language (self-modifying code, jumping into the middle of an instruction, etc...).
Forth might work better than C, but tbh, assembly code is more straightforward and easier to read than Forth ;)

I believe most of the 8bit microcontrollers from this era have no good optimizing compilers that get close to what competent practitioners achieve with assembly. I think it has to do with having complex addressing modes making the C stack fairly inefficient.

For an 8 bit Z80 based hardware project like this, assembly is a valid choice. The reason is performance. You'll lose significant performance with a compiler or interpreter.

The quickest way to redraw a screen or otherwise copy a memory region on Spectrum of is to use POP/PUSH instructions while flipping the stack pointer. Good luck getting that with C.

assembly is the only choice. The Z80 processor is a twisty collection of registers, none alike. It is pretty much the opposite of what a, for example, C compiler is looking for.
In fact C compilers are _notoriously_ bad at producing code for the Z80.
